BACKGROUND

There are numerous steps in the development of any novel, desirablesoybean variety. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germ plasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possess the traits to meetthe program goals. The breeder's goal is to combine in a single varietyan improved combination of desirable traits. These traits may includehigher seed yield, resistance to diseases and insects, reducing the timeto crop maturity, tolerance to drought and/or heat, altered fatty acidprofiles, abiotic stress tolerance, improvements in compositionaltraits, and better agronomic characteristics. These product developmentprocesses, which lead to the final step of marketing and distribution,can take from six to twelve years from the time the first cross is madeuntil the finished seed is delivered to the farmer for planting.Therefore, development of new varieties is a time-consuming process thatrequires precise planning, efficient use of resources, and a minimum ofchanges in direction.

A continuing goal of soybean breeders is to develop stable, highyielding soybean varieties that are agronomically sound with maximalyield over one or more different conditions and environments.

A score of 1 indicates severe galling of the rootsystem which can cause pre-mature death from decomposition of the rootsystem (susceptible). A score of 9 indicates that there is little to nogalling of the roots (resistant). Preliminary scores are reported asdouble digits, for example ‘55’ indicates a preliminary score of 5 onthe scale of 1 to 9.

Severity is visually scored on roots ina range from 1 to 9 comparing all genotypes in a given experiment toknown resistant and susceptible checks. The score is determined byvisually scoring the roots for presence or absence of galling in acontrolled chamber bioassay. A score of 1 indicates severe galling ofthe root system which can cause premature death from decomposition ofthe root system (susceptible). A score of 9 indicates that there islittle to no galling of the roots (resistant). Preliminary scores arereported as double digits, for example ‘55’ indicates a preliminaryscore of 5 on the scale of 1 to 9.

Scores are from 1 to 9 andindicate visual observations of the number of female SCN nematodes ascompared to known susceptible genotypes in the test. A score of 1indicates the number of female SCN nematodes is greater than 71% of thenumber observed on known susceptible varieties and cause yield loss,while a score of 9 indicates the number of female SCN nematodes is lessthan 7% of the number observed on known susceptible varieties, and theline shows strong SCN resistance. Preliminary scores are reported asdouble digits, for example ‘55’ indicates a preliminary score of 5 onthe scale of 1 to 9.

Soybean Variety 5PDST38

Soybean variety 5PDST38 has been self-pollinated a sufficient number ofgenerations, with careful attention to uniformity of plant type toensure a sufficient level of homozygosity and phenotypic stability. Thevariety has been increased with continued observation for uniformity. Novariant traits have been observed or are expected.

Soybean variety 5PDST38 has shown uniformity and stability for alltraits, as described in the following variety description information. Avariety description of soybean variety 5PDST38 is provided in Table 1.Traits reported are average values for all locations and years orsamples measured. Preliminary scores are reported as double digits, forexample ‘55’ indicates a preliminary score of 5 on the scale of 1 to 9.

Soybean variety 5PDST38, being substantially homozygous, can bereproduced by planting seeds of the variety, growing the resultingsoybean plants under self-pollinating or sib-pollinating conditions, andharvesting the resulting seed, using techniques familiar to theagricultural arts. Development of soybean variety 5PDST38 is shown inthe breeding history summary in Table 2.

Genetic Marker Profile

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety ora related variety, or which can be used to determine or validate apedigree. Genetic marker profiles can be obtained by techniques such asrestriction fragment length polymorphisms (RFLPs), randomly amplifiedpolymorphic DNAs (RAPDs), arbitrarily primed polymerase chain reaction(AP-PCR), DNA amplification fingerprinting (DAF), sequence characterizedamplified regions (SCARs), amplified fragment length polymorphisms(AFLPs), simple sequence repeats (SSRs) also referred to asmicrosatellites, single nucleotide polymorphisms (SNPs), or genome-wideevaluations such as genotyping-by-sequencing (GBS). For example, seeCregan et al. (1999) “An Integrated Genetic Linkage Map of the SoybeanGenome” Crop Science 39:1464, and Berry et al. (2003) “AssessingProbability of Ancestry Using Simple Sequence Repeat Profiles:Applications to Maize Inbred Lines and Soybean Varieties” Genetics165:331.

Favorable genotypes and or marker profiles, optionally associated with atrait of interest, may be identified by one or more methodologies. Insome examples one or more markers are used, including but not limited toAFLPs, RFLPs, ASH, SSRs, SNPs, indels, padlock probes, molecularinversion probes, microarrays, sequencing, and the like. In somemethods, a target nucleic acid is amplified prior to hybridization witha probe. In other cases, the target nucleic acid is not amplified priorto hybridization, such as methods using molecular inversion probes (see,for example Hardenbol et al. (2003) Nat Biotech 21:673-678). In someexamples, the genotype related to a specific trait is monitored, whilein other examples, a genome-wide evaluation including but not limited toone or more of marker panels, library screens, association studies,microarrays, gene chips, expression studies, or sequencing such aswhole-genome resequencing and genotyping-by-sequencing (GBS) may beused. In some examples, no target-specific probe is needed, for exampleby using sequencing technologies, including but not limited tonext-generation sequencing methods (see, for example, Metzker (2010) NatRev Genet 11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such assequencing by synthesis (e.g., Roche 454 pyrosequencing, IIlumina GenomeAnalyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation(e.g., SOLiD from Applied Biosystems, and Polnator system from AzcoBiotech), and single molecule sequencing (SMS or third-generationsequencing) which eliminate template amplification (e.g., Helicossystem, and PacBio RS system from Pacific BioSciences). Furthertechnologies include optical sequencing systems (e.g., Starlight fromLife Technologies), and nanopore sequencing (e.g., GridION from OxfordNanopore Technologies). Each of these may be coupled with one or moreenrichment strategies for organellar or nuclear genomes in order toreduce the complexity of the genome under investigation via PCR,hybridization, restriction enzyme (see, e.g., Elshire et al. (2011) PLoSONE 6: e19379), and expression methods. In some examples, no referencegenome sequence is needed in order to complete the analysis.

Methods are provided of characterizing soybean variety 5PDST38, or avariety comprising the phenotypic characteristics, morphologicalcharacteristics, physiological characteristics or combination thereof ofsoybean variety 5PDST38. A method comprising isolating nucleic acids,such as DNA, from a plant, a plant part, plant cell or a seed of thesoybean variety disclosed herein is provided. The method can includemechanical, electrical and/or chemical disruption of the plant, plantpart, plant cell or seed, contacting the disrupted plant, plant part,plant cell or seed with a buffer or solvent, to produce a solution orsuspension comprising nucleic acids, optionally contacting the nucleicacids with a precipitating agent to precipitate the nucleic acids,optionally extracting the nucleic acids, and optionally separating thenucleic acids such as by centrifugation or by binding to beads or acolumn, with subsequent elution, or a combination thereof. If DNA isbeing isolated, an RNase can be included in one or more of the methodsteps. The nucleic acids isolated can comprise all or substantially allof the genomic DNA sequence, all or substantially all of the chromosomalDNA sequence or all or substantially all of the coding sequences (cDNA)of the plant, plant part, or plant cell from which they were isolated.The amount and type of nucleic acids isolated may be sufficient topermit whole genome sequencing of the plant from which they wereisolated or chromosomal marker analysis of the plant from which theywere isolated.

The methods can be used to produce nucleic acids from the plant, plantpart, seed or cell, which nucleic acids can be, for example, analyzed toproduce data. The data can be recorded. The nucleic acids from thedisrupted cell, the disrupted plant, plant part, plant cell or seed orthe nucleic acids following isolation or separation can be contactedwith primers and nucleotide bases, and/or a polymerase to facilitate PCRsequencing or marker analysis of the nucleic acids. In some examples,the nucleic acids produced can be sequenced or contacted with markers toproduce a genetic profile, a molecular profile, a marker profile, ahaplotype, or any combination thereof. In some examples, the geneticprofile or nucleotide sequence is recorded on a computer readablemedium. In other examples, the methods may further comprise using thenucleic acids produced from plants, plant parts, plant cells or seeds ina plant breeding program, for example in making soybean crossing,selection and/or advancement decisions in a breeding program. Crossingincludes any type of plant breeding crossing method, including but notlimited to outcrossing, selfing, backcrossing, locus conversion,introgression and the like.

In some examples, one or more markers are used to characterize and/orevaluate a soybean variety. Particular markers used for these purposesare not limited to any particular set of markers, but are envisioned toinclude any type of marker and marker profile which provides a means ofdistinguishing varieties. For example, one method of comparison is touse only homozygous loci for 5PDST38.

Primers and PCR protocols for assaying these and other markers aredisclosed in Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University) which is available online. Inaddition to being used for identification of soybean variety 5PDST38 andplant parts and plant cells of variety 5PDST38, the genetic profile maybe used to identify a soybean plant produced through the use of 5PDST38or to verify a pedigree for progeny plants produced through the use of5PDST38. The genetic marker profile is also useful in breeding anddeveloping backcross conversions.

Provided is a soybean plant characterized by molecular and physiologicaldata obtained from the representative sample of said variety depositedwith the American Type Culture Collection (ATCC). Thus, plants, seeds,or parts thereof, having all or substantially all of the physiological,morphological, and/or phenotypic characteristics of soybean variety5PDST38 are provided. Further provided is a soybean plant formed by thecombination of the disclosed soybean plant or plant cell with anothersoybean plant or cell and comprising the homozygous alleles of thevariety. A soybean plant comprising all of the physiological,morphological and/or phenotypic characteristics of soybean variety5PDST38 can be combined with another soybean plant in a soybean breedingprogram. In some examples the other soybean plant comprises all of thephysiological, morphological and/or phenotypic characteristics ofsoybean variety 5PDST38.

In some examples, a plant, a plant part, or a seed of soybean variety5PDST38 is characterized by producing a molecular profile. A molecularprofile includes but is not limited to one or more genotypic and/orphenotypic profile(s). A genotypic profile includes but is not limitedto a marker profile, such as a genetic map, a linkage map, a traitmarker profile, a SNP profile, an SSR profile, a genome-wide markerprofile, a haplotype, and the like. A molecular profile may also be anucleic acid sequence profile, and/or a physical map. A phenotypicprofile includes but is not limited to one or more phenotypic traits, aprotein expression profile, a metabolic profile, an mRNA expressionprofile, and the like.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. A marker system based on SSRs can be highlyinformative in linkage analysis relative to other marker systems in thatmultiple alleles may be present. Another advantage of this type ofmarker is that, through use of flanking primers, detection of SSRs canbe achieved, for example, by using the polymerase chain reaction (PCR),thereby eliminating the need for labor-intensive Southern hybridization.PCR detection is done using two oligonucleotide primers flanking thepolymorphic segment of repetitive DNA to amplify the SSR region.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which correlates to the number of base pairsof the fragment. While variation in the primer used or in laboratoryprocedures can affect the reported fragment size, relative values shouldremain constant regardless of the specific primer or laboratory used.When comparing varieties, it is preferable if all SSR profiles areperformed in the same lab.

Primers used are publicly available and may be found in the Soybasedatabase or Unigene database (each available online), Cregan (1999 CropScience 39:1464-1490), Choi et al. (2007 Genetics 176:685-696), andHyten et al. (2010 Crop Sci 50:960-968). See also, PCT Publication WO99/31964, U.S. Pat. Nos. 6,162,967, 7,288,386.

The SSR profile of soybean plant 5PDST38 can be used to identify plantscomprising 5PDST38 as a parent, since such plants will comprise the samehomozygous alleles as 5PDST38. Because the soybean variety isessentially homozygous at all relevant loci, most loci should have onlyone type of allele present. In contrast, a genetic marker profile of anF1 progeny should be the sum of those parents, e.g., if one parent washomozygous for allele X at a particular locus, and the other parenthomozygous for allele Y at that locus, then the F1 progeny will be XY(heterozygous) at that locus. Subsequent generations of progeny producedby selection and breeding are expected to be of genotype XX(homozygous), YY (homozygous), or XY (heterozygous) for that locusposition. When the F1 plant is selfed or sibbed for successive filialgenerations, the locus should be either X or Y for that position.

In addition, plants and plant parts substantially benefiting from theuse of 5PDST38 in their development, such as 5PDST38 comprising abackcross conversion, transgene, or genetic sterility factor, may beidentified by having a molecular marker profile with a high percentidentity to 5PDST38. Such a percent identity might be 90%, 91%, 92%,93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, or 99.9% identical to 5PDST38.

The SSR profile of variety 5PDST38 also can be used to identifyessentially derived varieties and other progeny varieties developed fromthe use of 5PDST38, as well as cells and other plant parts thereof.Plants include, for example, any plant having at least 90%, 91%, 92%,93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, or 99.9% of the markers in theSSR profile, and that retain 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%,98%, 99%, 99.5%, or 99.9% of the physiological and morphologicalcharacteristics of variety 5PDST38 when grown under the same conditions.Such plants may be developed, for example, using the markers identifiedin WO00/31964, U.S. Pat. Nos. 6,162,967 and 7,288,386. Progeny plantsand plant parts produced using 5PDST38 may be identified by having amolecular marker profile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%,60%, 65%, 70%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%,86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or99.5% genetic contribution from soybean variety 5PDST38, as measured byeither percent identity or percent similarity. Such progeny may befurther characterized as being within a pedigree distance of 5PDST38,such as within 1, 2, 3, 4, or 5 or less cross-pollinations to a soybeanplant other than 5PDST38, or a plant that has 5PDST38 as a progenitor.Unique molecular profiles may be identified with other molecular toolssuch as SNPs and RFLPs.

Introduction of a New Trait or Locus into 5PDST38

Variety 5PDST38 represents a new genetic variety into which a locus ortrait may be introduced or introgressed. Transformation and backcrossingrepresent two methods that can be used to accomplish such anintrogression.

Provided are soybean plants further comprising a locus conversion whichplant may otherwise comprise, express or have all or essentially all ofthe morphological and physiological characteristics of the soybeanvariety 5PDST38. In certain embodiments, the soybean plant is defined ascomprising a single locus conversion. The converted soybean plant mayotherwise comprise, express or have all or essentially all of themorphological and physiological characteristics of the soybean variety5PDST38. By all or essentially all of the morphological andphysiological characteristics, it is meant that all of thecharacteristics of a plant are recovered that are otherwise present whencompared in the same environment, other than an occasional variant traitthat might arise during backcrossing or direct introduction of atransgene or specific genetic modification.

In certain embodiments, the single locus conversion may comprise atransgenic gene which has been introduced by genetic transformation intothe soybean variety 5PDST38 or a progenitor thereof. In certainembodiments, the single locus conversion may comprise a dominant orrecessive allele. The locus conversion may confer potentially any traitupon the single locus converted plant, including herbicide resistance,insect resistance, resistance to bacterial, fungal, or viral disease,male fertility or sterility, and improved nutritional quality.

It is known to those of skill in the art that, by way of the techniqueof backcrossing, one or more traits may be introduced into a givenvariety while otherwise retaining essentially all of the traits of thatvariety. A backcross conversion of 5PDST38 occurs when DNA sequences areintroduced through backcrossing with 5PDST38 utilized as the recurrentparent. Naturally occurring, modified and transgenic DNA sequences maybe introduced through backcrossing techniques. A backcross conversionmay produce a plant with a trait or locus conversion in at least two ormore backcrosses, including at least 2 backcrosses, at least 3backcrosses, at least 4 backcrosses, at least 5 backcrosses, at least 6backcrosses or more, depending at least in part on the differencesbetween the parents of the original cross. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion.

The complexity of the backcross conversion method depends on the type oftrait being transferred (a single gene or closely linked genes comparedto unlinked genes), the level of expression of the trait, the type ofinheritance (cytoplasmic or nuclear), dominant or recessive traitexpression, and the types of parents included in the cross. It isunderstood by those of ordinary skill in the art that for single genetraits that are relatively easy to classify, the backcross method iseffective and relatively easy to manage. (See Hallauer et al., in Cornand Corn Improvement, Sprague and Dudley, Third Ed. 1998). Desiredtraits that may be transferred through backcross conversion include, butare not limited to, sterility (nuclear and cytoplasmic), fertilityrestoration, nutritional enhancements, drought tolerance, nitrogenutilization, altered fatty acid profile, low phytate, industrialenhancements, disease resistance (bacterial, fungal, or viral), insectresistance, and herbicide resistance. In addition, a recombination siteitself, such as an FRT site, Lox site, or other site specificintegration site, may be inserted by backcrossing and utilized fordirect insertion of one or more genes of interest into a specific plantvariety. A single locus conversion may contain several transgenes ormodifications, such as a transgene or modification for diseaseresistance and for herbicide resistance. The gene for herbicideresistance may be used as a selectable marker and/or as a phenotypictrait. A single locus conversion of site specific integration systemallows for the integration of multiple genes at a known recombinationsite in the genome. At least one, at least two or at least three andless than ten, less than nine, less than eight, less than seven, lessthan six, less than five or less than four locus conversions may beintroduced into the plant by backcrossing, introgression ortransformation to express the desired trait, while the plant, or a plantgrown from the seed, plant part or plant cell, otherwise retains thephenotypic characteristics of the deposited seed when grown under thesame environmental conditions.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest can be accomplished by direct selection for atrait associated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the trait(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withsubsequent selection for the trait.

An example of backcrossing to introduce a trait into a starting varietyis described in U.S. Pat. No. 6,140,556. The procedure described in U.S.Pat. No. 6,140,556 can be summarized as follows: The soybean varietyknown as Williams '82 [Glycine max L. Merr.] (Reg. No. 222, PI 518671)was developed using backcrossing techniques to transfer a locuscomprising the Rps1 gene to the variety Williams (Bernard and Cremeens,1988, Crop Sci., 28:1027). Williams '82 is a composite of four resistantlines from the BC6F3 generation, which were selected from 12field-tested resistant lines from Williams×Kingwa. The variety Williamswas used as the recurrent parent in the backcross and the variety Kingwawas used as the source of the Rps1 locus. This gene locus confersresistance to 19 of the 24 races of the fungal agent phytophthora rootrot. The F1 or F2 seedlings from each backcross round were tested forresistance to the fungus by hypocotyl inoculation using the inoculum ofrace 5. The final generation was tested using inoculum of races 1 to 9.In a backcross such as this, where the desired characteristic beingtransferred to the recurrent parent is controlled by a major gene whichcan be readily evaluated during the backcrossing, it is common toconduct enough backcrosses to avoid testing individual progeny forspecific traits such as yield in extensive replicated tests. In general,four or more backcrosses are used when there is no evaluation of theprogeny for specific traits, such as yield. As in this example, lineswith the phenotype of the recurrent parent may be composited without theusual replicated tests for traits such as yield, protein or oilpercentage in the individual lines. The variety Williams '82 iscomparable to the recurrent parent variety Williams in its traits exceptresistance to phytophthora rot. For example, both varieties have arelative maturity of 38, indeterminate stems, white flowers, brownpubescence, tan pods at maturity and shiny yellow seeds with black tolight black hila.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are recovered aftersuccessive backcrosses, such as at least one, at least two, at leastthree, at least 4 or at least 5 backcrosses. The number of backcrossesnecessary can be reduced with the use of molecular markers. Otherfactors, such as a genetically similar donor parent, may also reduce thenumber of backcrosses necessary. As noted by Poehlman, backcrossing iseasiest for simply inherited, dominant, and easily recognized traits.

One process for adding or modifying a trait or locus in soybean variety5PDST38 comprises crossing 5PDST38 plants grown from 5PDST38 seed withplants of another soybean variety that comprises a desired trait lackingin 5PDST38, selecting F1 progeny plants that possess the desired traitor locus to produce selected F1 progeny plants, crossing the selectedprogeny plants back to 5PDST38 plants to produce backcross1 (BC1)progeny plants. The BC1F1 progeny plants that have the desired trait andthe morphological characteristics of soybean variety 5PDST38 areselected and backcrossed to 5PDST38 to generate BC2F1 progeny plants.Additional backcrossing and selection of progeny plants with the desiredtrait will produce BC3F1, BC4F1, BC5F1, . . . BCxF1 generations ofplants. The backcross populations of 5PDST38 may be furthercharacterized as having the phenotypic, physiological and/ormorphological characteristics of soybean variety 5PDST38, such as listedin Table 1, as determined at the 5% significance level when grown in thesame environmental conditions and/or may be characterized by percentsimilarity or identity to 5PDST38 as determined by SSR or othermolecular markers. The above method may be utilized with fewerbackcrosses in appropriate situations, such as when the donor parent ishighly related or molecular markers are used in one or more selectionsteps. Desired traits that may be used include those nucleic acids knownin the art, some of which are listed herein, that will affect traitsthrough nucleic acid expression or inhibition. Desired loci also includethe introgression of FRT, Lox, and/or other recombination sites for sitespecific integration. Desired loci further include QTLs, which may alsoaffect a desired trait.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing 5PDST38with the introgressed trait or locus with a different soybean plant andharvesting the resultant first generation progeny soybean seed.

Transgenes and transformation methods provide means to engineer thegenome of plants to contain and express heterologous genetic elements,including but not limited to foreign genetic elements, additional copiesof endogenous elements, and/or modified versions of native or endogenousgenetic elements, in order to alter at least one trait of a plant in aspecific manner. Any heterologous DNA sequence(s), whether from adifferent species or from the same species, which are inserted into thegenome using transformation, backcrossing, or other methods known to oneof skill in the art are referred to herein collectively as transgenes.The sequences are heterologous based on sequence source, location ofintegration, operably linked elements, or any combination thereof. Oneor more transgenes of interest can be introduced into soybean variety5PDST38. Transgenic variants of soybean variety 5PDST38 plants, seeds,cells, and parts thereof or derived therefrom are provided. Transgenicvariants of 5PDST38 comprise the physiological and morphologicalcharacteristics of soybean variety 5PDST38, such as listed in Table 1 asdetermined at the 5% significance level when grown in the sameenvironmental conditions, and/or may be characterized or identified bypercent similarity or identity to 5PDST38 as determined by SSR or othermolecular markers. In some examples, transgenic variants of soybeanvariety 5PDST38 are produced by introducing at least one transgene ofinterest into soybean variety 5PDST38 by transforming 5PDST38 with apolynucleotide comprising the transgene of interest. In other examples,transgenic variants of soybean variety 5PDST38 are produced byintroducing at least one transgene by introgressing the transgene intosoybean variety 5PDST38 by crossing.

In one example, a process for modifying soybean variety 5PDST38 with theaddition of a desired trait, said process comprising transforming asoybean plant of variety 5PDST38 with a transgene that confers a desiredtrait is provided. Therefore, transgenic 5PDST38 soybean cells, plants,plant parts, and seeds produced from this process are provided. In someexamples one more desired traits may include traits such as herbicideresistance, insect resistance, disease resistance, decreased phytate,modified fatty acid profile, modified fatty acid content, carbohydratemetabolism, protein content, or oil content. The specific gene may beany known in the art or listed herein, including but not limited to apolynucleotide conferring resistance to an ALS-inhibitor herbicide,imidazolinone, sulfonylurea, protoporphyrinogen oxidase (PPO)inhibitors, hydroxyphenyl pyruvate dioxygenase (HPPD) inhibitors,glyphosate, glufosinate, triazine, 2,4-dichlorophenoxyacetic acid(2,4-D), dicamba, broxynil, metribuzin, or benzonitrile herbicides; apolynucleotide encoding a Bacillus thuringiensis polypeptide, apolynucleotide encoding a phytase, a fatty acid desaturase (e.g., FAD-2,FAD-3), galactinol synthase, a raffinose synthetic enzyme; or apolynucleotide conferring resistance to soybean cyst nematode, brownstem rot, Phytophthora root rot, soybean mosaic virus, sudden deathsyndrome, or other plant pathogen.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88; and Armstrong (1999) “The First Decade of Maize Transformation: AReview and Future Perspective” Maydica 44:101-109. In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence or apre-existing transgenic sequence including regulatory elements, codingand non-coding sequences. These methods can be used, for example, totarget nucleic acids to pre-engineered target recognition sequences inthe genome. Such pre-engineered target sequences may be introduced bygenome editing or modification. As an example, a genetically modifiedplant variety is generated using “custom” or engineered endonucleasessuch as meganucleases produced to modify plant genomes (see e.g., WO2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Anothersite-directed engineering method is through the use of zinc fingerdomain recognition coupled with the restriction properties ofrestriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet.11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. Atranscription activator-like (TAL) effector-DNA modifying enzyme (TALEor TALEN) is also used to engineer changes in plant genome. See e.g.,US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Bochet al., (2009), Science 326(5959): 1509-12. Site-specific modificationof plant genomes can also be performed using the bacterial type IICRISPR (clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated) system. See e.g., Belhaj et al., (2013), PlantMethods 9: 39; The Cas9/guide RNA-based system allows targeted cleavageof genomic DNA guided by a customizable small noncoding RNA in plants(see e.g., WO 2015026883A1).

The modified variety 5PDST38 or a plant otherwise derived from variety5PDST38 may be further characterized as having all or essentially all ofthe phenotypic characteristics, or all or essentially all of themorphological and physiological characteristics of variety 5PDST38,and/or may be characterized by percent identity to 5PDST38 as determinedby molecular markers, such as SSR markers or SNP markers. By essentiallyall of the phenotypic characteristics or morphological and physiologicalcharacteristics, it is meant that all of the characteristics of a plantare recovered that are otherwise present when compared in the sameenvironment, other than an occasional variant trait that might ariseduring backcrossing or direct introduction of a transgene or specificgenetic modification.

Plant transformation methods may involve the construction of anexpression vector. Such a vector or recombinant construct comprises aDNA sequence that contains a coding sequence, such as a protein and/orRNA coding sequence under the control of or operatively linked to aregulatory element, for example a promoter. The vector or construct maycontain one or more coding sequences and one or more regulatoryelements.

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed soybean variety into anelite soybean variety, and the resulting backcross conversion plantwould then contain the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences.

A genetic map can be generated that identifies the approximatechromosomal location of the integrated DNA molecule, for example viaconventional restriction fragment length polymorphisms (RFLP),polymerase chain reaction (PCR) analysis, simple sequence repeats (SSR),and single nucleotide polymorphisms (SNP). For exemplary methodologiesin this regard, see Glick and Thompson, Methods in Plant MolecularBiology and Biotechnology, pp. 269-284 (CRC Press, Boca Raton, 1993).

Wang et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome”, Science (1998)280:1077-1082, and similar capabilities are increasingly available forthe soybean genome. Map information concerning chromosomal location isuseful for proprietary protection of a subject transgenic plant. Ifunauthorized propagation is undertaken and crosses made with other germplasm, the map of the integration region can be compared to similar mapsfor suspect plants to determine if the latter have a common parentagewith the subject plant. Map comparisons could involve hybridizations,RFLP, PCR, SSR, sequencing or combinations thereof, all of which areconventional techniques. SNPs may also be used alone or in combinationwith other techniques.

Likewise, plants can be genetically engineered to express variousphenotypes of agronomic interest. Through the transformation of soybean,the expression of genes can be altered to enhance disease resistance,insect resistance, herbicide resistance, agronomic, grain quality, andother traits. Transformation can also be used to insert DNA sequenceswhich control or help control male-sterility. DNA sequences native tosoybean as well as non-native DNA sequences can be transformed intosoybean and used to alter levels of native or non-native proteins.Various promoters, targeting sequences, enhancing sequences, and otherDNA sequences can be inserted into the genome for the purpose ofaltering the expression of proteins. Reduction of the activity ofspecific genes (also known as gene silencing or gene suppression) isdesirable for several aspects of genetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to, knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook Ch.118 (Springer-Verlag 1994)); antisense technology (see, e.g., U.S. Pat.Nos. 5,107,065; 5,453,566; and 5,759,829); co-suppression (e.g., Taylor(1997) Plant Cell 9:1245; Jorgensen (1990) Trends Biotech 8:340-344;Flavell (1994) PNAS USA 91:3490-3496; Finnegan et al.

(1992)        PNAS USA 89:2624; and WO99/64579 (Genes for Desaturases to Alter        Lipid Profiles in Corn).    -   (2) Elevating oleic acid via FAD-2 gene modification and/or        decreasing linolenic acid via FAD-3 gene modification (see U.S.        Pat. Nos. 6,063,947; 6,323,392; 6,372,965; and International        Publication WO93/11245).    -   (3) Altering conjugated linolenic or linoleic acid content, such        as in WO01/12800.    -   (4) Altering LEC1, AGP, mi1ps, and various 1pa genes such as        Ipa1, Ipa3, hpt or hggt. For example, see WO02/42424;        WO98/22604; WO03/011015; U.S. Pat. Nos. 6,423,886; 6,197,561;        and, 6,825,397; US2003/0079247; US2003/0204870; WO02/057439;        WO03/011015; and Rivera-Madrid et al. (1995) PNAS USA        92:5620-5624.

B) Altered phosphate content, for example, by:

-   -   (1) Introduction of a phytase-encoding gene would enhance        breakdown of phytate, adding more free phosphate to the        transformed plant. For example, see Van Hartingsveldt et        al. (1993) Gene 127:87, for a disclosure of the nucleotide        sequence of an Aspergillus niger phytase gene.    -   (2) Modulating a gene that reduces phytate content. For example        in maize this could be accomplished by cloning and then        re-introducing DNA associated with one or more of the alleles,        such as the LPA alleles, identified in maize mutants        characterized by low levels of phytic acid, such as in        WO05/113778; and/or by altering inositol kinase activity as in        WO02/059324; U.S. Pat. No. 7,067,720; WO03/027243;        US2003/0079247; WO99/05298; U.S. Pat. Nos. 6,197,561; 6,291,224;        and 6,391,348; WO98/45448; WO99/55882; and WO01/04147.

In other examples the genes relate to altered stachyose orraffinose levels in soybean, including, for example, those described inU.S. Pat. No. 8,471,107; WO93/007742; and WO98/045448. The fatty acidmodification genes mentioned herein may also be used to affect starchcontent and/or composition through the interrelationship of the starchand oil pathways.

(D) Altered antioxidant content or composition, such as alteration oftocopherol or tocotrienols. For example, see U.S. Pat. Nos. 6,787,683;7,154,029; and WO00/68393 involving the manipulation of antioxidantlevels, and WO03/082899 through alteration of a homogentisate geranyltransferase (hggt).

4. Genes that Control Male-Sterility

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al., and chromosomal translocationsas described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al. U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene conferring male fertility tobe transcribed. Male sterile soybean lines and characterization arediscussed in Palmer (2000) Crop Sci 40:78-83, and Jin et al. (1997) SexPlant Reprod 10:13-21.

This includes the introduction of at least one FRT sitethat may be used in the FLP/FRT system and/or a Lox site that may beused in the Cre/Lox system. For example, see Lyznik et al. (2003) PlantCell Rep 21:925-932; and WO99/25821. Other systems that may be usedinclude the Gin recombinase of phage Mu (Maeser et al.

Development of Soybean Sublines

Sublines of 5PDST38 may also be developed and are provided. Although5PDST38 contains substantially fixed genetics and is phenotypicallyuniform with no off-types expected, there still remains a smallproportion of segregating loci either within individuals or within thepopulation as a whole. Sublining provides the ability to select forthese loci, which have no apparent morphological or phenotypic effect onthe plant characteristics, but may have an effect on overall yield. Forexample, the methods described in U.S. Pat. Nos. 5,437,697, 7,973,212,and US2011/0258733, and US2011/0283425 may be utilized by a breeder ofordinary skill in the art to identify genetic loci that are associatedwith yield potential to further purify the variety in order to increaseits yield. A breeder of ordinary skill in the art may fix agronomicallyrelevant loci by making them homozygous in order to optimize theperformance of the variety. The development of soybean sublines and theuse of accelerated yield technology is a plant breeding technique.

Soybean varieties such as 5PDST38 are typically developed for use inseed and grain production. However, soybean varieties such as 5PDST38also provide a source of breeding material that may be used to developnew soybean varieties. Plant breeding techniques known in the art andused in a soybean plant breeding program include, but are not limitedto, recurrent selection, mass selection, bulk selection, backcrossing,pedigree breeding, open pollination breeding, restriction fragmentlength polymorphism enhanced selection, genetic marker enhancedselection, making double haploids, and transformation. Oftencombinations of these techniques are used. The development of soybeanvarieties in a plant breeding program requires, in general, thedevelopment and evaluation of homozygous varieties. There are manyanalytical methods available to evaluate a new variety. The oldest andmost traditional method of analysis is the observation of phenotypictraits but genotypic analysis may also be used.

Methods for producing a soybean plant by crossing a first parent soybeanplant with a second parent soybean plant wherein the first and/or secondparent soybean plant is variety 5PDST38 are provided. A method ofproducing hybrid soybean seeds is provided comprising crossing thesoybean variety 5PDST38 with a second, distinct soybean plant that isnonisogenic to the soybean variety 5PDST38. In particular embodiments ofthe invention, the crossing comprises the steps of a) planting seeds ofsoybean variety 5PDST38 and a second, distinct soybean plant, b)cultivating the soybean plants grown from the seeds until the plantsbear flowers; c) cross-pollinating a flower on one of the two plantswith the pollen of the other plant, and d) harvesting the seedsresulting from the cross-pollinating. Also provided are methods forproducing a soybean plant having substantially all of the morphologicaland physiological characteristics of variety 5PDST38, by crossing afirst parent soybean plant with a second parent soybean plant whereinthe first and/or the second parent soybean plant is a plant havingsubstantially all of the morphological and physiological characteristicsof variety 5PDST38 set forth in Table 1, as determined at the 5%significance level when grown in the same environmental conditions. Theother parent may be any soybean plant, such as a soybean plant that ispart of a synthetic or natural population. Any such methods usingsoybean variety 5PDST38 include but are not limited to selfing, sibbing,backcrossing, mass selection, pedigree breeding, bulk selection, hybridproduction, crossing to populations, and the like. These methods arewell known in the art and some of the more commonly used breedingmethods are described below.

Pedigree breeding starts with the crossing of two genotypes, such as5PDST38 or a soybean variety having all of the morphological andphysiological characteristics of 5PDST38, and another soybean varietyhaving one or more desirable characteristics that is lacking or whichcomplements 5PDST38. If the two original parents do not provide all thedesired characteristics, other sources can be included in the breedingpopulation. In the pedigree method, superior plants are selfed andselected in successive filial generations. In the succeeding filialgenerations, the heterozygous allele condition gives way to thehomozygous allele condition as a result of inbreeding. Typically, in thepedigree method of breeding, five or more successive filial generationsof selfing and selection are practiced: e.g., F1→F2; F2→F3; F3→F4;F4→F5; etc. In some examples, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or moregenerations of selfing and selection are practiced. After a sufficientamount of inbreeding, successive filial generations will serve toincrease seed of the developed variety. Typically, the developed varietycomprises homozygous alleles at about 95% or more of its loci.

In addition to being used to create backcross conversion populations,backcrossing can also be used in combination with pedigree breeding. Asdiscussed previously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety (the donor parent) to adeveloped variety (the recurrent parent), which has good overallagronomic characteristics yet may lack one or more other desirabletraits. However, the same procedure can be used to move the progenytoward the genotype of the recurrent parent but at the same time retainmany components of the non-recurrent parent by stopping the backcrossingat an early stage and proceeding with selfing and selection. Forexample, a soybean variety may be crossed with another variety toproduce a first generation progeny plant. The first generation progenyplant may then be backcrossed to one of its parent varieties to create aBC1F1. Progeny are selfed and selected so that the newly developedvariety has many of the attributes of the recurrent parent and yetseveral of the desired attributes of the donor parent. This approachleverages the value and strengths of both parents for use in new soybeanvarieties.

Therefore, in some examples a method of making a backcross conversion ofsoybean variety 5PDST38, comprising the steps of crossing a plant ofsoybean variety 5PDST38 or a soybean variety having all of themorphological and physiological characteristics of 5PDST38 with a donorplant possessing a desired trait to introduce the desired trait,selecting an F1 progeny plant containing the desired trait, andbackcrossing the selected F1 progeny plant to a plant of soybean variety5PDST38 are provided. This method may further comprise the step ofobtaining a molecular marker profile of soybean variety 5PDST38 andusing the molecular marker profile to select for a progeny plant withthe desired trait and the molecular marker profile of 5PDST38. Themolecular marker profile can comprise information from one or moremarkers. In one example the desired trait is a mutant gene or transgenepresent in the donor parent. In another example, the desired trait is anative trait in the donor parent.

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. Variety 5PDST38, and/or a soybeanvariety having all of the morphological and physiologicalcharacteristics of 5PDST38, is suitable for use in a recurrent selectionprogram. The method entails individual plants cross pollinating witheach other to form progeny. The progeny are grown and the superiorprogeny selected by any number of selection methods, which includeindividual plant, half-sib progeny, full-sib progeny, and selfedprogeny. The selected progeny are cross pollinated with each other toform progeny for another population. This population is planted and,again, superior plants are selected to cross pollinate with each other.Recurrent selection is a cyclical process and therefore can be repeatedas many times as desired. The objective of recurrent selection is toimprove the traits of a population. The improved population can then beused as a source of breeding material to obtain new varieties forcommercial or breeding use, including the production of a syntheticcultivar. A synthetic cultivar is the resultant progeny formed by theintercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection, seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk, andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self pollination, directed pollinationcould be used as part of the breeding program.

Mutation breeding is another method of introducing new traits intosoybean variety 5PDST38 or a soybean variety having all of themorphological and physiological characteristics of 5PDST38. Methods forintrogressing or introducing a mutant trait into soybean variety 5PDST38and to the soybean plants and plant parts produced by those methods areprovided. A mutagen such as ethyl methanesulfonate, gamma radiation andsodium azide may be applied to the plant or seed such that the resultingplant or seed comprises a genome mutation. Mutations that occurspontaneously or that are artificially induced can be useful sources ofvariability for a plant breeder. The goal of artificial mutagenesis isto increase the rate of mutation for a desired characteristic. Mutationrates can be increased by many different means including temperature,long-term seed storage, tissue culture conditions, radiation; such asX-rays, gamma rays (e.g., cobalt 60 or cesium 137), neutrons, (productof nuclear fission by uranium 235 in an atomic reactor), beta radiation(emitted from radioisotopes such as phosphorus 32 or carbon 14),ultraviolet radiation (preferably from 2500 to 2900 nm), or chemicalmutagens such as base analogues (5-bromo-uracil), related compounds(8-ethoxy caffeine), antibiotics (streptonigrin), alkylating agents(sulfur mustards, nitrogen mustards, epoxides, ethylenamines, sulfates,sulfonates, sulfones, lactones), azide, hydroxylamine, nitrous acid, oracridines. Once a desired trait is observed through mutagenesis, thetrait may then be incorporated into existing germplasm by traditionalbreeding techniques. Details of mutation breeding can be found in“Principles of Cultivar Development” Fehr, 1993, Macmillan PublishingCompany. In addition, mutations created in other soybean plants may beused to produce a backcross conversion of 5PDST38 that comprises suchmutation.

Molecular markers, which include markers identified through the use oftechniques such as isozyme electrophoresis, restriction fragment lengthpolymorphisms (RFLPs), randomly amplified polymorphic DNAs (RAPDs),arbitrarily primed polymerase chain reaction (AP-PCR), DNA amplificationfingerprinting (DAF), sequence characterized amplified regions (SCARs),amplified fragment length polymorphisms (AFLPs), simple sequence repeats(SSRs), single nucleotide polymorphisms (SNPs), and sequencing may beused in plant breeding methods utilizing 5PDST38.

Isozyme electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker & Olsen (“Molecular Linkage Map ofSoybean (Glycine max L. Merr.)”, p. 6.131-6.138, in S. J. O'Brien (ed.)Genetic Maps: Locus Maps of Complex Genomes. (1993) Cold Spring HarborLaboratory Press. Cold Spring Harbor, N.Y.), developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD (random amplified polymorphic DNA), three classicalmarkers, and four isozyme loci. See also, Shoemaker “RFLP Map ofSoybean” pp 299-309 (1994), in R. L. Phillips and I. K. Vasil (ed.)describing DNA-based markers in plants. Kluwer Academic Press Dordrecht,the Netherlands.

SSR technology is an efficient and practical marker technology; moremarker loci can be routinely used and more alleles per marker locus canbe found using SSRs in comparison to RFLPs. For example, Diwan andCregan, described highly polymorphic microsatellite loci in soybean withas many as 26 alleles (Diwan and Cregan (1997) Theor Appl Genet95:220-225). Single nucleotide polymorphisms (SNPs) may also be used toidentify the unique genetic composition of 5PDST38 and progeny varietiesretaining or derived from that unique genetic composition. Variousmolecular marker techniques may be used in combination to enhanceoverall resolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan et al. (1999) Crop Sci 39:1464-1490. Sequences and PCRconditions of SSR loci in soybean, as well as the most current geneticmap, may be found in the Soybase database available online.

One use of molecular markers is quantitative trait loci (QTL) mapping.QTL mapping is the use of markers which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plantgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which variety 5PDST38 or a soybean varietyhaving all of the phenotypic, morphological and/or physiologicalcharacteristics of 5PDST38 is a parent can be used to produce doublehaploid plants. Double haploids are produced by the doubling of a set ofchromosomes (1N) from a heterozygous plant to produce a completelyhomozygous individual. For example, see US Patent Publication No.2003/0005479. This can be advantageous because the process omits thegenerations of selfing needed to obtain a homozygous plant from aheterozygous source. Double haploid technology in soybean is discussedin Croser et al. (2006) Crit Rev Plant Sci 25:139-157; and Rodrigues etal. (2006) Brazilian Arc Biol Tech 49:537-545.

In some examples a process for making a substantially homozygous 5PDST38progeny plant by producing or obtaining a seed from the cross of 5PDST38and another soybean plant and applying double haploid methods to the F1seed or F1 plant or to any successive filial generation is provided.Based on studies in maize, and currently being conducted in soybean,such methods would decrease the number of generations required toproduce a variety with similar genetics or characteristics to 5PDST38.See Bernardo & Kahler (2001) Theor Appl Genet 102:986-992.

In particular, a process of making seed retaining the molecular markerprofile of soybean variety 5PDST38 is contemplated, such processcomprising obtaining or producing F1 seed for which soybean variety5PDST38 is a parent, inducing doubled haploids to create progeny withoutthe occurrence of meiotic segregation, obtaining the molecular markerprofile of soybean variety 5PDST38, and selecting progeny that retainthe molecular marker profile of 5PDST38.

Methods using seeds, plants, cells, or plant parts of variety 5PDST38 intissue culture are provided, as are the cultures, plants, parts, cells,and/or seeds derived therefrom. Tissue culture of various tissues ofsoybeans and regeneration of plants therefrom is well known and widelypublished. For example, see Komatsuda et al. (1991) Crop Sci 31:333-337;Stephens et al. “Agronomic Evaluation of Tissue-Culture-Derived SoybeanPlants” (1991) Theor Appl Genet 82:633-635; Komatsuda et al. “Maturationand Germination of Somatic Embryos as Affected by Sucrose and PlantGrowth Regulators in Soybeans Glycine gracilis Skvortz and Glycine max(L.) Merr.” (1992) Plant Cell Tissue and Organ Culture 28:103-113; Dhiret al. “Regeneration of Fertile Plants from Protoplasts of Soybean(Glycine max L. Merr.): Genotypic Differences in Culture Response”(1992) Plant Cell Rep 11:285-289; Pandey et al. “Plant Regeneration fromLeaf and Hypocotyl Explants of Glycine wightii (W. and A.) VERDC. var.longicauda” (1992) Japan J Breed 42:1-5; and Shetty et al. “Stimulationof in Vitro Shoot Organogenesis in Glycine max (Merrill.) by Allantoinand Amides” (1992) Plant Sci 81:245-251; U.S. Pat. Nos. 5,024,944 and5,008,200. Thus, another aspect is to provide cells which upon growthand differentiation produce soybean plants having the physiological andmorphological characteristics of soybean variety 5PDST38.

Themethod can include a step of contacting the seed with a composition tocoat the surface of the seed or to adhere the composition to the seed.The composition may be applied to the seed in a seed treatment at anytime from harvesting of the seed to sowing of the seed. The compositionmay be applied using methods including but not limited to mixing in acontainer, mechanical application, tumbling, spraying, misting, andimmersion. Thus, the composition may be applied as a powder, acrystalline, a ready-to-use, a slurry, a mist, and/or a soak. For ageneral discussion of techniques used to apply fungicides to seeds, see“Seed Treatment,” 2d ed., (1986), edited by K. A Jeffs (chapter 9). Thecomposition to be used as a seed treatment can comprise one or more of apesticide, a fungicide, an insecticide, a nematicide, an antimicrobial,an inoculant, a growth promoter, a polymer, a flow agent, a coating, orany combination thereof. General classes or family of seed treatmentagents include triazoles, anilides, pyrazoles, carboxam ides, succinatedehydrogenase inhibitors (SDHI), triazolinthiones, strobilurins, amides,and anthranilic diamides. In some examples, the seed treatment comprisestrifloxystrobin, azoxystrobin, metalaxyl, metalaxyl-m, mefenoxam,fludioxinil, imidacloprid, thiamethoxam, thiabendazole, ipconazole,penflufen, sedaxane, prothioconazole, picoxystrobin, penthiopyrad,pyraclastrobin, xemium, Rhizobia spp., Bradyrhizobium spp. (e.g., B.japonicum), Bacillus spp. (e.g., B. firmus, B. pumilus, B. subtilis),lipo-chitooligosaccharide, clothianidin, cyazapyr, rynaxapyr, abamectin,and any combination thereof. In some examples the seed treatmentcomprises trifloxystrobin, metalaxyl, imidacloprid, Bacillus spp., andany combination thereof. In some examples the seed treatment comprisespicoxystrobin, penthiopyrad, cyazapyr, ranaxapyr, and any combinationthereof. In some examples, the seed treatment improves seed germinationunder normal and/or stress environments, early stand count, vigor,yield, root formation, nodulation, and any combination thereof. In someexamples seed treatment reduces seed dust levels, insect damage,pathogen establishment and/or damage, plant virus infection and/ordamage, and any combination thereof.

Soybean seeds, plants, and plant parts of variety 5PDST38 may be used orprocessed for food, animal feed, or a raw material(s) for industry.Seeds from variety 5PDST38 can be crushed, or a component of the seedscan be extracted in order to make a plant product, such as proteinconcentrate, protein isolate, soybean hulls, meal, flour, or oil for afood or feed product. Methods of producing a plant product or acommodity product, such as protein concentrate, protein isolate, soybeanhulls, meal, flour, or oil for a food or feed product by processing theplants, plant parts or grain disclosed herein are provided. Alsoprovided are the protein concentrate, protein isolate, soybean hulls,meal, flour, or oil produced by the methods.

Soybean is also used as a food source for both animals and humans.Soybean is widely used as a source of protein for animal feeds forpoultry, swine, and cattle, or specialty pet foods. For humanconsumption soybean meal is made into soybean flour which is processedto protein concentrates used for meat extenders. Production of edibleprotein ingredients from soybean offers a healthy, less expensivereplacement for animal protein in meats and dairy products. Duringprocessing of whole soybeans, the fibrous hull is removed and the oil isextracted. The remaining soybean meal is a combination of carbohydratesand approximately 50% protein.

Oil extracted from soybeans is used for cooking oil, margarine, andsalad dressings. Soybean oil has a typical composition of 11% palmitic,4% stearic, 25% oleic, 50% linoleic, and 9% linolenic fatty acidcontent. Fatty acid composition can be altered, for example, throughtransformation, breeding or a combination thereof, for improvedoxidative stability and nutrition. For example, oleic acid can be raisedto at least 70% or 75% of the total fatty acid content, and linolenicacid can be reduced to less than 5% or 3% of the total fatty acidcontent. Oil with 3% or less linolenic acid is classified as lowlinolenic oil, oil with less than 1% linolenic acid is classified asultra-low linolenic oil. Oil with 70% or higher of oleic acid isclassified as high oleic oil.

Industrial uses of soybean oil, which is typically subjected to furtherprocessing, include ingredients for paints, plastics, fibers,detergents, cosmetics, lubricants, and biodiesel fuel. Soybean oil maybe split, inter-esterified, sulfurized, epoxidized, polymerized,ethoxylated, or cleaved. To produce oil, the harvested soybeans arecracked, adjusted for moisture content, rolled into flakes, and then theoil is solvent-extracted. The oil extract is refined, optionally blendedand/or hydrogenated. The mixture of triglycerides can be split andseparated into pure fatty acids, which can be combined withpetroleum-derived alcohols or acids, nitrogen, sulfonates, chlorine, orwith fatty alcohols derived from fats and oils.

Soybeans are also used as a food source for both animals and humans.Soybeans are widely used as a source of protein for animal feed. Thefibrous hull is removed from whole soybean and the oil is extracted. Theremaining meal is a combination of carbohydrates and approximately 50%protein. This remaining meal is heat treated under well-establishedconditions and ground in a hammer mill. Soybean is a predominant sourcefor livestock feed components.

In addition to soybean meal, soybean can be used to produce soy flour.Soy flour refers to defatted soybeans where special care was takenduring desolventizing to minimize protein denaturation and to retain ahigh nitrogen solubility index (NSI) in making the flour. Soy flour isthe typical starting material for production of soy concentrate and soyprotein isolate. Defatted soy flour is obtained from solvent extractedflakes, and contains less than 1% oil. Full-fat soy flour is made fromwhole beans and contains about 18% to 20% oil. Low-fat soy flour is madeby adding back some oil to defatted soy flour. The lipid content varies,but is usually between 4.5-9%. High-fat soy flour can also be producedby adding soybean oil to defatted flour at the level of 15%.Lecithinated soy flour is made by adding soybean lecithin to defatted,low-fat or high-fat soy flours to increase dispersibility and impartemulsifying properties.

For human consumption, soybean can be used to produce edible ingredientswhich serve as an alternative source of dietary protein. Common examplesinclude milk, cheese, and meat substitutes. Additionally, soybean can beused to produce various types of fillers for meat and poultry products.Vitamins and/or minerals may be added to make soy products nutritionallymore equivalent to animal protein sources as the protein quality isalready roughly equivalent.
